152 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic

370 check the result for NULL. Most set bfd_error to no_memory and
371 return in that case; a few are harder to fix, and are marked

706 * aoutx.h (aout_link_check_ar_symbols): Correct test for whether

742 bfd_coff_symname_in_debug returns true, don't put symbol name in

768 symbol has a value in the ECOFF symbol but not in the BFD symbol,
769 keep the value in the ECOFF symbol. This helps gas.
771 * linker.c (_bfd_generic_link_output_symbols,

850 bfd_som_set_subsection_attributes): Change parameters from char
851 to int. Following a prototype with an old-style function definition
852 in the presence of widened parameters is a GCC-ism not supported

911 .pdata section based on lnnoptr field, not section header.
912 (alpha_relocate_section): Don't bother to check if r_symndx >= 0,
913 since it is unsigned.
914 (ecoffalpha_little_vec): Use alpha_ecoff_object_p rather than
916 * ecoff.c (ecoff_new_section_hook): Set alignment_power field of
918 (ecoff_compute_section_file_positions): Save the size of the
919 .pdata section in the line_filepos field, and actually align the

922 calling ecoff_compute_section_file_positions.

927 vstamp used by the first object file in the link.

932 for a created common section.
933 (_bfd_generic_link_add_one_symbol): Likewise.
935 * elfcode.h (swap_out_syms): Use elf_section_from_bfd_section to
936 get the index of a common section, rather than always using

2251 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
2252 Handle symbol number of zero.
2254 * reloc.c (enum bfd_reloc_code_real): Added
2255 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
2256 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
2257 * bfd-in2.h: Rebuilt.
2258 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
2259 BFD_RELOC_MIPS_LITERAL.
2260 * elf32-mips.c (mips_reloc_map): Handle new relocs.
2261 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
2264 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
2265 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
2266 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
2267 MY_bfd_seclet_link): Define.
2268 (MY_bfd_reloc_type_lookup): Rename from
2269 MY_reloc_howto_type_lookup.
2270 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
2271 (MY(vec)): Use JUMP_TABLE rather than listing functions.
2272 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
2273 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
2274 terms of MY, because that causes a recusive invocation of CAT when
2275 expanded within JUMP_TABLE, and ANSI compilers don't expand
2277 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
2278 MY_reloc_howto_type_lookup, and don't define in terms of MY.
2279 (MY_canonicalize_reloc): Don't define in terms of MY.
2280 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
2281 than listing functions.

2285 * config.bfd: Use m68k-elf for m68*-*-sysv4*.
